Answer:
52
Step-by-step explanation:
f(n) is purely based on the previous value of f(n), or f(n-1), so we can start with f(1) and work our way up. We know f(1) = 2, so to find f(2), we plug f(1) into
f(n-1)²+3 to get
f(1)²+3 = 2²+3 = 4+3=7
Thus, f(2) =7. Similarly,
f(3) = f(3-1)²+3 = f(2)² + 3 -= 7² + 3= 52
Answer:
Suppose you travel a distance of 100 miles, and it takes 1 1/2 hours to do it. Your average speed is then 100 miles divided by 1.5 hours which equals 66.67 miles per hour.

Question 1:
For this case we must find
knowing that:

By definition we have that, be two functions f (x) and g (x), then the composite function of f with g is:
![(g_ {0} f) (x) = g [f (x)]](https://tex.z-dn.net/?f=%28g_%20%7B0%7D%20f%29%20%28x%29%20%3D%20g%20%5Bf%20%28x%29%5D)
In this case, they ask us for the function composed of g with f:
![(f_ {0} g) (x) = f [g (x)]](https://tex.z-dn.net/?f=%28f_%20%7B0%7D%20g%29%20%28x%29%20%3D%20f%20%5Bg%20%28x%29%5D)
So, we have:

ANswer:

Question 2:
For this case, we must find the inverse function of
, given by: 
To do this, replace g(x) with y:

We exchange variables:

We solve for "y":

Replace "y" with 
So, we have:

Answer:

Question 3:
For this case, we have by definition, the domain of a function f (x), is the set of all the values for which the function is defined.
We must find the domain of the following function:

It is observed that the function is not defined for 
Then the domain is given by all the values of x, except 0.
for any integer n
Answer:
All numbers, except
Answer:
24
Step-by-step explanation:
it is 24 because 12 and 8 both go into 24 and that is the lowest LCD possible for those numbers.
